I stand corrected. However, the "dome" on top of the Abramsprise is not the bridge dome. According to the viewindow pull-out scene, the iBridge is much lower in the saucer than the dome. Methinks the dome is simply a sensor array of some kind.
Also, the firmentation room where Uhura was seems to be an extremely large room with a very high ceiling. It would appear to be much higher than the ceiling of the iBridge, yet when looking at the impges of the ibridge area on the saucer of the Abramsprise, the iBridge deck tapers down toward the rear from the iBridge which is at the front. In other words, the brewery room won't fit within the physical confines of that deck.
